So, the Omer nail gun is misfiring too often, and when it does it tends to explode the nylon nail and jam the striker requiring a brief disassembly and cleaning. It has been used quite a lot so we’re looking for general wear issues. The smooth top plate and the bottom channel plate don’t seem worn. The Omer nail gun is the only one for shooting the nylon nails and it’s an expensive piece of equipment, so it’s absolutely worth carefully repairing.
Talked to the mfg today. It sounds like the striker is probably worn and the front is rounded out instead of a flat surface. We can check for this under the microscope. If so, it’s a matter of dressing the face of the striker back to a flat face. It needs to be done carefully and take off as little metal as possible, as well as using a dressing method that won’t itself round out or slant the striker. There may be a way to do it with fine-grit wet sandpaper on a flat surface, but we’ve got a manual mill, so probably the mill.
Any redressing method for the striker will require disassembly to remove the striker. Maintenance guide with parts explosion here:
